BACKGROUND

Filters are widely used in purification at many fields, such as central air conditioning and ventilation systems, pharmaceuticals, hospital, electronics, food and other industry, which can also be used as the front-end filtration of high-efficiency particulate air filters to reduce the load of high-efficiency particulate air filters and prolong their service life.
At present, the filter frame is usually fixed with screws, which requires tools to disassemble during replacement, resulting in time-consuming and labor-consuming. Further, it is also very easy to accumulate damage to the filter frame during the process of replacement with tools such as screwdriver.
In addition, most of the traditional filters are disposable, with large transportation volume, high cost, high scrap disposal cost and waste of resources. A few of the traditional filters are replaceable, but the replacement process is very cumbersome and difficult to operate, and the cost of recycling after one-time scrap is high.
